[U.S. Congressman Keith Self Votes Against the National Defense Authorization Act Due to Concerns Over CBDC] U.S. Republican Congressman Keith Self tweeted that central bank digital currencies (CBDCs) are the ultimate tool for government surveillance and control over Americans' finances, granting the federal government the power to track, restrict, and even freeze transactions. Keith Self stated that ignoring financial privacy is unacceptable, which is why he voted against the National Defense Authorization Act and will continue to fight to ensure that CBDCs never come into existence.
